The isolation work during maintenance or inspection of nuclear power plants is very important for safety and a large number of isolation items are carried out. A computer support system is very effective to improve the reliability of the isolation. In Fugen nuclear power station, an isolation support system (ISS) has been developed. This system adopts a computer aided design (CAD) technique for isolation planning and controlling. With the help of this system, the user can control the state of the plant quickly by monitoring P&IDs on a workstation, resolve the conflicts between the isolation items, plan isolation work very fast and save labor cost for planning. The objectives of the development thereby have been achieved: improvement of safety and reliability, optimization of isolation work and so on. This system was put into practical operation in July 1989.
